Application 'led June 13, 1922, Serial No: 567,932. Renewed December 27, 1924.

To all whom z't may cof/wem.'

Be it known that we, JEAN U. KORE, a subjectof the King of Rumania, residing at and whose post-ottice address is No. 1834 Broadway, in the city, county, and State of New York, andAssAD M. MALLUK, a citizen of the Republic of France, residing at and whose post-oce address is No. 170 West 72nd Street, in the city', county, and State of lNew York, have invented certain new and useful Improvements in Vacuum Containers; and we do hereby declare the following to be a full, clear, andeXact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to vacuum containers, and has for one object the provision, in a single unitary structure, of means for carrying two liquids or solids having widely diiferent temperatures,` and for preserving these temperatures during a substantial period of time. Anotheraobject of the invention is to provide means for e'ectively protecting such containers against the breaking of the fragile vacuumpreceptacle, or vessel, under certain conditions.

In order to attain these objects We provide a two compartment vacuum insulated receptacle, of glass, or other suitable material, the compartments being arranged end to end, and having a single common vacuum space separating them. Both compartments must hold a reasonable amount of food, and it is necessary, therefore,that the container as a whole be made somewhat larger than the 'usual vacuum containers. It has been found preferable to increase the length of the structure rather than the diameter, but, inasmuch as this increase in length weakens the structure, it is desirable to provide some means' for reinforcing the receptacle at its center opposite thecommon vacuum space.

The double compartment vacuum insulated receptacle is inserted within a protective casing of metal, which casing is also provided. with a reinforcing ring centrally disposed with respect to its ends.

- In vacuum containers as at resent constructed, if one is accidentally al owed to fall upon the ground, striking on its side, the vacuum receptacle which is more or lessl fragile, will in the majority of cases be that the liability of breakage in this mani,

ner may be greatly reduced by the provision of resillent protective members, comprising rods 'or strips which are more or less flexible, running longitudinally of the casing and detachably mounted on the exterior about mid-way between the ends of the casing. If a container thus protected should be accidentally dropped and the container strike upon its side, on account of the shape 'of the resilient protective members, their ends will strike first and the greater portion of theshock will be absorbed by the flexing of these members, and, in some cases, in detaching them from the casing.

These resilient .protective members may conveniently be made in the form of eating utensils, such as knives, forks and spoons, thereby serving a double purpose.

Although this means for protecting a vacuum container may be used with one having` a single compartment, its greatest use is in connection with the double container inasmuch as it is necessary to provide extraordinary means to prevent breakage.

In the accompanying drawings We have illustrated our invention in connection with a vacuum container of the bottle type, that is, both of the compartments are provided with openings which are more or less restricted. It will be understood, however, that either one or both of the compartments of this container may be constructed with openings which are less restricted in order to facilitate the introduction of solid food instead of liquid.

In these drawings:

Fig. 1 'is a longitudinal sectional View of our improved double compartment container, and

Fig. 2 is a view in transverse section taken on line 2 2 of Fig. 1, showing the distribution of the resilient protective members around the periphery of the container.

In these'drawings the vacuum insulated receptacle in indicated at 3 and isprovided with the separate food compartments 4e and 5. This receptacle, or vessel, is insulated against the passage of heat either to or from the vessel in the ordinary manner, that is, by means of double walls 6 and 7 with the space 8 intermediate these walls evacuated. The common insulating space 9 which sepavso rates the compartments 4 and 5 is incommunication'with 'the space 8 so that the vessel may be evacuated by connection with the vacuum pump at a single pointand the vessel can, therefore, be sealed by means of a single seal. In order to support the iu-l terior ends of the compartments 4 and 5, it is necessary to join the wall 6 with the wall 7 at a relatively few points as indicated at 10'.

Another very satisfactory means of supporting the compartments is by the use of an elastic ring of cork, or similar material, interposed between the walls 6v and 7.

As mentioned above, on .account of thev length of the vacuum receptacle 3 and theJ fact that the inner wall 6 is not-continuous from end to end, it is desirable to reinforce the receptacle by means of an exterior band 12 of cork, vulcanized rubber, or the like.`

13 represents the protective metal casing whichv surrounds the vacuum vessel into which the vessel may be inserted or removed by unscrewing the section 14 at the threads 15. Washers 16 are provided at each end of the vacuum receptacle which, in cooperation with the band 12 resiliently support the vacuum vessel within the metal car*- ing 13.

It is very of the container as much as possible, Kand on this account the metal casing 13 is made relatively thin and is reinforced midway between its ends by means ofring 16 of relatively light, strong elastic material, such as hard rubber.

We now come to the auxiliary or supplemental means' for protecting the container which comprises the resilient members 17 suitably spaced around the outside of the casing 13 as clearly shown in Fig. 2., These resilient protective members are detachably mounted upon the casing 13 about midway between the ends thereof, and may be conviently securedto the protecting@ ring 16. The means for attaching the members 17 to ring 16 preferably comprises a pair of snap fasteners 18 for each member which eifectively secures thel members 17 to the oo ntainer but at the same time oifers some considerable resistance to the detachment of the members so asto assist in absorbing the shock due to the fall of the container. The members may, however, be detached with the fingers with comparative ease. As shown in the drawings these resilient protective members are made in the form of knives, forks and spoons, there being two of each of these articles.

Each'of the food compartments 4 and 5 1s provided with the usual stopper 19 of cor or other suitable material, and Vthese Stoppers, kas well as the ends of the vacuum vessel are rotected by means of the metal 4caps 20 w ich arefof suchsize and shape desirable to reduce the weight -to, a protective member on the inside of y that they also serve the purpose of drinking cu s.

IlVith the vacuum container constructed in accordance with our invention either liquid or solid food, or a combination of the two may be preserved at approximately the temperature at which they were originally introduced into the container for a considerable number of hours, and if the container is accidentally dropped, landing upon its side, the shock of the fall is materially reduced by the auxiliary protecting members provided. Moreover, these "members may be used as eating utensils. Furthermore, the construction of the two food compartments in a single unitary structure having a single exterior wall and separated by a common vacuum space considerably reduces the cost of manufacture on account of the saving in material, and the saving of one operation of exhaustion.

It is to be understood-that the size and proportions of the various parts may be varied without departing fromthe principle of the invention which is not limited to the particular embodiment shown and described, but is intended to include such modifications thereof as fall within the scope of the appended claims. v

We claim: Y 95 f 1. In a device of. the class described, a vacuum vessel having an outer wall land an inner wall formed into a plurality Ofcompartments placed end to end, said compartments being held in spaced relation with 10 said'outer wall by a plurality of rigid supports disposed near the inner ends of said compartments, a protecting casing surrounding said vessel and in spaced relation there- 0 1 5 said casing, and a second protective member on the outside of said casing, both of said protective members being disposed opposite said rigid supports.
